Abstract: APPARATUS FOR PRODUCING A PLASMA SOURCE OF HIGH-INTENSITY RADIATION IN THE X-RAY REGION                Abstract of the Disclosure A virtually punctiform plasma source of high-intensity radiation in the X-ray region is produced at the open downstream end of a gas-filled discharge space defined by and between concentric cylindrical inner and outer electrodes.  At the closed upstream end, the electrodes which define this discharge space are directly connected to a low-inductance high-power switch which serves for momentarily connecting the electrodes to a source of stored electric energy.  At the closed end of the discharge space, the inner electrode is concentrically surrounded by an insulator which has a high coefficient of secondary-electron emission.  In closely opposed adjacency to the insulator region of the inner electrode is an annular emission electrode which is at the potential of the outer electrode, the emission electrode being positioned at close radial offset from the insulator, and the offset being less than the mean free path in the gas of the discharge space. gas discharge is produced in the discharge space at a well-defined distance downstream from the emitter electrode, and the discharge is a homogeneous plasma layer, which moves toward the open downstream end of the discharge space and there forms a plasma focus of extremely high particle density and small diameter, which focus provides the plasma source of X-radiation.

Abstract: ABSTRACT        A vehicle control and guidance system in which a desired route for the vehicle is stored in the vehicle in the form of co-ordinates in a ground reference frame. The 'vectors' between these junction points are divided by successive reference points into incremental vectors, the reference points being generated ahead of the vehicle at regular intervals.  A dead reckoning system predicts the position of the vehicle at the end of each interval and this estimate is corrected a using a Kalman filter, by an independent fixed-target detection system using a scanning laser.   The error between the estimated vehicle position and the local incremental vector provides a steering angle correction for the vehicle and the vehicle speed is dependent upon the lag of the vehicle behind the generation of reference points.

Abstract: A METHOD OF TRANSFERRING IMPURITIES FROM REGION TO REGION                 OF A SEMICONDUCTOR DEVICE            Abstract The contact to the source-drain region in advanced memory arrays has a width of tune order of the minimum feature size.  The source-drain has similar minimum feature dimensions in width to keep the array optimally dense.  Thus this contact is made "headless" and requires a "line on line" alignment.  Some offset in forming the window is inevitable and that offset exposes the channel stop.  The contact then shorts to the substrate.           Using a polysilicon transfer layer with an appropriate post anneal the region immediately under the contact and along the window sidewall can be autodoped sufficiently to avoid shorts to the substrate, and provide a continuous electrical path for the deposited contact.

Abstract: CIRCULAR SPRAY BOOTH Spray particles are removed in at least a 180.degree. surround of an article traversing an arcuate path in the interior of a spray booth. The booth includes a water wash extending vertically for a height greater than the work area and spray area and preferably extends upwardly to the area of an overhead conveyor. Air flow is maintained at a substantially constant velocity to carry overspray particles into the water wash and away from the article and a water particle eliminator eliminates water particles from the cleaned air being discharged. The preferred booth comprises a plurality of adjacent units set at angles to each other to define a polygon of at least 180.degree. with a planar water wash means being provided in each unit. The preferred water wash includes vertically extending t staggered panels each washed with a film of water with the air flowing through gaps between adjacent panels and then flowing down through a second spray water wash. A sludge remover may be used with a water reservoir tank to allow long operation in contrast to the downtime for frequent dry filter replacement and the cost of filter replacement experienced in conventional circular spray booths. A conveyor protection device may be used which discharges positively pressure air from a housing about the conveyor with the air flow in the booth pulling this blown air away from the spray areas and booth portal and into and through the water wash.
